ENGINE, FUEL/PROPULSION SYSTEM, ELECTRICAL SYSTEM
WHILE DRIVING THE VEHICLE SUDDENLY THE ACCELERATOR STARTED TO HAVE A DELAYED RESPONSE. PRESSING THE ACCELERATOR WOULD NOT DO ANYTHING FOR BETWEEN 3 TO 5 SECOND AFTER THE CAR WAS STOPPED. AFTER THE DELAY, THE CAR WOULD RESPOND AND WAS DRIVABLE, BUT AFTER EVERY SUBSEQUENT STOP, THE 3 TO 5 SECOND DELAY WOULD RETURN. THIS CONTINUED FOR THE 20 MILES THAT I DROVE TO THE DEALERSHIP TO HAVE THEM LOOK AT THE CAR AND REPAIR IT. I BELIEVE THIS UNRESPONSIVENESS OF THE ACCELERATOR TO BE A DANGEROUS CONDITION AS IT PREVENTED ME FROM BEING ABLE TO DRIVING NORMALLY AND COULD HAVE PREVENTED ME FROM MOVING MY VEHICLE IF IT WAS STOPPED AND A SITUATION REQUIRED IT TO BE MOVED QUICKLY. AT THIS TIME THIS OCCURRED THE FOLLOWING WARNING LIGHTS APPEARED ON THE DASH. THE CHECK ENGINE LIGHT CAME ON. THE ESP WARNING LIGHT CAME ON, THE ESP SYSTEM "OFF" LIGHT CAME ON, AND A MESSAGE STATING THAT "PRESAFE FUNCTIONS WERE UNAVAILABLE" APPEARED ON THE DASH BOARD COMPUTER SCREEN. THIS WAS THE SECOND TIME THIS HAPPENED TO ME. THE FIRST TIME WAS AT THE BEGINNING OF APRIL. I PULLED THE CAR OVER. RESTARTED THE CAR AND THE CONDITION FIXED ITSELF. THIS TIME, RESTARTING THE CAR DID NOT CLEAR THE CONDITION. *JS

ENGINE, FUEL/PROPULSION SYSTEM
THIS HAS HAPPENED MULTIPLE TIMES STARTING IN JAN. 2014 AND MOST RECENTLY APRIL 15, 2014: COME TO A STOP AT RED LIGHT (OR STOP SIGN) AND WHEN I STEP ON GAS TO GO WHEN LIGHT TURNS GREEN, ETC., NO POWER OR, AT MOST, CAR BARELY COASTS TO SHOULDER OF ROAD. IT DOES NOT SOUND LIKE THE ENGINE ENGAGES. I TURN THE IGNITION OFF AND THEN ON AGAIN AND THE CAR RUNS. THIS HAPPENS WHEN ECO STOP/START FUNCTION IS ON AND ALSO HAPPENS WHEN IT IS OFF. I AM AFRAID TO DRIVE THE CAR BECAUSE THIS HAPPENS WITHOUT WARNING. I COULD BE DRIVING THE CAR FOR A WEEK WITH NO PROBLEM AND THEN IT HAPPENS.

FUEL SYSTEM, GASOLINE, VEHICLE SPEED CONTROL, ENGINE
I HAVE PARTIAL VIDEO IF THIS INCIDENT. INCIDENT OCCURRED AT 991 ODOMETER MILES. AFTER DRIVING APPROX. ~300 MOSTLY CONTIGUOUS, FLAT, RURAL HIGHWAY MILES IN-BETWEEN LINCOLN, NE AND ST. LOUIS, MO (HEADING TO ATLANTA, GA) IN APPROX. 30 WEATHER ON DRY PAVEMENT, THE ENGINE STOPPED PRODUCING ENOUGH ENGINE POWER TO PROPEL THE VEHICLE AT THE 70-75 MPH THAT I WAS TRAVELING. AT APPROX. 60-65 MPH, I APPLIED ADDITIONAL PRESSURE TO THE GAS PEDAL WHICH WAS NOT EFFECTIVE. PUSHING THE GAS PEDAL TO THE FLOOR DID NOTHING EXCEPT, OCCASIONALLY, THE TRANSMISSION WOULD SWITCH QUICKLY IN-BETWEEN THE SAME TWO GEARS, WHICH REGISTERED SLIGHTLY ON THE TACHOMETER BUT DID NOTHING TO ACCELERATE THE VEHICLE OR MAINTAIN SPEED. IT ALMOST FELT AS IF THE TRACTION CONTROL WAS ACTIVATING (BUT MALFUNCTIONING) DESPITE THE GROUND BEING TOTALLY DRY. BY APPROX. 50 MPH I WAS BEING FLANKED AND TAILGATED BY TWO CLEARLY DISGRUNTLED SEMI-TRUCKS AS I TRIED TO PULL OVER TO THE RIGHT. THE VEHICLE SEEMINGLY WOULD MAINTAIN A MAX. OF 35 MPH. UPON RESTARTING THE CAR (NORMAL START), LETTING IT IDLE (NORMAL IDLE), AND THEN ATTEMPTING TO DRIVE TO A SAFER LOCATION, ITS ACCELERATION FELT RESTRICTED AT LOWER RPMS, BUT IT DID BACK UP TO HIGHWAY SPEED AND THE RESTRICTED FEELING ENDED UP BEING TEMPORARY. THE NEAREST DEALER WAS MB OF MARION, IL., APPROX. ANOTHER 200-300 MILES AWAY. ON THE WAY TO THIS DEALERSHIP, THE SAME MALFUNCTION OCCURRED AGAIN ABOUT 50-75 MILES LATER. I WENT THROUGH THE SAME PROCESS AND RESTARTED THE VEHICLE. AT THE MARION, IL DEALER, THE MECHANIC FOUND THE FOLLOWING CODE IN THE COMPUTER: PO29921 - BOOST PRESSURE OF TURBOCHARGER TOO LOW. THE MECHANIC AT THE MARION, IL DEALER AND, LATER, AT ANOTHER DEALER CLOSER TO WHERE I LIVE (MERCEDES OF SOUTH ATLANTA) WAS NOT ABLE TO REPLICATE THIS CODE AND THEREFORE NO REPAIRS HAVE EVER BEEN ATTEMPTED OR MADE. THIS ISSUE HAS NOT RE-OCCURRED HERE IN GEORGIA. *TR

VEHICLE SPEED CONTROL, SERVICE BRAKES
I PURCHASED A NEW NEW NEW MERCEDES CLA-250C AUTOMOBILE LATE SEPTEMBER 2013. IN MID-OCTOBER I EXPERIENCED UN-COMMANDED ACCELERATION TO ABOVE 5500 RPM. THIS CEASED JUST AS I WAS ABOUT TO APPLY BRAKING. THE CAR THEN BEHAVED NORMALLY. *TR ON CHRISTMAS NIGHT I EXPERIENCED UN-COMMANDED BRAKING WHENEVER I BACKED OFF THE ACCELERATOR PEDAL, THE FORCE OF BRAKING BEING PROPORTIONAL TO THE DEGREE OF LIFT-OFF FROM THE ACCELERATOR. I WAS ABLE TO BRING THE CAR TO A COMPLETE STOP WITHOUT TOUCHING THE BRAKE PEDAL. AT THAT POINT I GROUNDED THE CAR. ON JANUARY 7, 2014 I INFORMED MERCEDES-BENZ ABOUT THE ABOVE. I AM PREPARED TO PROVIDE FURTHER INFORMATION REGARDING THE ABOVE EVENTS AND MY CORRESPONDENCE WITH MERCEDES-BENZ USA SHOULD YOU DESIRE. *TR

ELECTRONIC STABILITY CONTROL (ESC), VEHICLE SPEED CONTROL, ENGINE
1ST- ON FEB 11TH & 12TH MY 2014 CLA WHICH WAS PURCHASED AT THE MB OF PEMBROKE PINES HAD BEEN TOWED TO THE MB OF POMPANO, FL DEALERSHIP BECAUSE OF THE EPS LIGHTS, "INOPERATIVE" WARNING MESSAGES THAT WERE COMING UP AS WELL AS THE STALLING AND DELAYED ACCELERATION, WHICH I TOOK PHOTOS OF. IT WAS TOWED TO POMPANO FORM MY JOB, MY CAR WAS KEPT AT THE DEALERSHIP FOR 4 DAYS (AS OPPOSED TO THE FEW HRS I WAS TOLD THAT IT WOULD TAKE TO FIX THE COMPUTER ISSUES). NOT ONLY WAS MY CAR IN THE SHOP FOR 3 DAYS, BUT A PART THAT HAD BEEN ORDERED,WHICH MEANS SOMETHING OBVIOUSLY WASN?T FUNCTIONING PROPERLY SO IT HAD TO BE REPLACED. 2ND - I PICKED UP MY VEHICLE ON SAT FEB 15TH FROM THE POMPANO, AFTER GETTING ONTO THE I95 AND DRIVING 2 MINS, THE SAME WARNING SIGNS CAME BACK UP. I EXITED DRIVING 15MPH AND TRYING TO KEEP THE VEHICLE STABLE. MR. MIKE RODRIGUEZ WAS INSTRUCTED TO TEST DRIVE THE VEHICLE, HOWEVER, WHEN HE DID SO THE WARNING SIGNALS WERE GONE. WHY? BECAUSE A SERVICE GUY RESTARTED THE VEHICLE AND DROVE IT INTO THE SERVICE AREA. BEING THAT THE SIGNAL WAS NO LONGER VISIBLE, THE GM SUGGESTED THAT IF THERE WAS EVER A SIGNAL SENT TO THE VEHICLE IT WOULD SHOW UP IN SOME SORT OF READING THEY WERE ABLE TO DO ON THE VEHICLE. WHEN THEY RETURNED, BOTH THE GM AND MR. RODRIGUEZ INFORMED US THAT THE VEHICLE SHOWED THEM THERE WAS NO SIGNAL THAT WAS SENT TO THE VEHICLE ALL DAY. I LITTERALLY JUST SAW IT NOT 30 MINS AGO. WE LEFT & ABOUT 2 MINS FROM MY HOME IN BOCA RATON, THE SIGNAL WAS BACK WITH VENGEANCE! AT THIS POINT I TOOK PICTURES. I PULLED INTO MY DRIVE WAY, BUT THIS TIME I LEFT THE VEHICLE RUNNING. 3RD -ON MARCH 2ND AT AROUND 2:45PM, AFTER ABOUT A WEEK OF HAVING MY VEHICLE BACK, I WAS DRIVING WHEN THE SAME WARNING SIGNS AND ACCELERATION PROBLEMS WERE BACK. I LEFT IT RUNNING WITH ALL THE SIGNALS UP AND IT HAD TO BE TOWED BACK. THIS IS A SUMMARY OF THE INCEDENTS.THIS HAS TO STOP! NOT SAFE! *TR

ELECTRICAL SYSTEM, VEHICLE SPEED CONTROL
TODAY I WAS DRIVING IN A PARKING LOT AND APPROACHED THE LIGHT TO EXIT AND MY DASHBOARD LIT UP WITH A PRESAFE SYSTEM FAILURE, SYSTEM IS INOPERATIVE AND MY CAR SLOWED DOWN CONSIDERABLY WHEN I TRIED TO ACCELERATE. I PULLED OVER AND TURNED THE ENGINE OFF AND THEN ON AGAIN AND THE ERROR CLEARED. THIS IS VERY DANGEROUS IF IT HAPPENS ON A HIGHWAY OR WHILE DRIVING ON A CROWDED STREET. I CALLED THE DEALER TODAY AND WAS TOLD IF THE ERROR WAS NOT CURRENTLY ON THE DASH THEY COULD NOT DO ANYTHING. I EXPLAINED THAT THIS WAS UNACCEPTABLE AND THEY NEEDED TO LOOK AT THE CAR. GOD FORBID I AM ON THE HIGHWAY AND IT DISABLED. LAST WEEK MY BROTHER-IN- LAW SAW THE SAME CAR DISABLED IN THE MIDDLE LANE OF THE HIGHWAY. I HOPE MB FIXES THIS PROBLEM FAST BEFORE SOMEONE IS SERIOUSLY HURT. *TR

SERVICE BRAKES, ELECTRONIC STABILITY CONTROL (ESC), ENGINE, VEHICLE SPEED CONTROL
ON SUNDAY, OCTOBER 27, AND TUESDAY, OCTOBER 29, 2013, MY VEHICLE LISTED ABOVE HAD WARNING LIGHTS COME ON THAT STATED, "PRE SAFE, FUNCTIONS LIMITED, INOPERATIVE." IN ADDITION TO THE WORDS, THE ESP AND ABS LIGHTS ILLUMINATED. I TOOK THE VEHICLE TO PENSKE MBZ IN WEST COVINA, CA, ON WEDNESDAY, OCTOBER 30. THEY REPAIRED THE VEHICLE BY DOING A SOFTWARE UPDATE. ON SATURDAY, NOVEMBER 2, 2013, THE CODES RETURNED AND I TOOK THE VEHICLE BACK TO WHERE I BOUGHT IT, ENCINO, CA, MBZ. I WAS TOLD THEY COULD NOT REPLICATE THE CODES AND THEY FOUND NO PROBLEM. THIS IS UNACCEPTABLE! THE VEHICLE IS STILL AT ENCINO MBZ AS THEY ARE TRYING TO REPLICATE THE PROBLEM. WHEN THIS MALFUNCTION OCCURS, THE VEHICLE LOSES POWER AND HAS VERY LIMITED ACCELERATION. IT HAS OCCURRED TWICE ON CITY STREETS AND TWICE ON THE FREEWAY, BOTH IN ECO AND SPORT MODE. ON THE CITY STREETS I AM ABLE TO JUST PULL TO THE CURB. ON THE FREEWAY, IT BECOMES A POSSIBLE LIFE THREATENING EMERGENCY. THERE IS ONLY VERY GRADUAL ACCELERATION, AND AT 65MPH, LIMITED ACCELERATION IS VERY DANGEROUS. THESE FOUR OCCURRENCES HAVE TAKEN PLACE IN LESS THAN A 10 DAY PERIOD AND NO LONG TERM REPAIR HAS YET BEEN ACCOMPLISHED! *TR
